The following table summarizes the cable requirement for 10/100/1000BASE-TX
connection:
10BASE-T 100 ohm Category 3, 4, 5 UTP/STP cable
100BASE-TX 100 ohm Category 5 UTP/STP cable
1000BASE-T 100 ohm Category 5 UTP/STP cable or better
(CAT 5E recommended)
Auto MDI/MDI-X function
The SNMP-FSH2602MG is equipped with Auto-MDI/MDI-X function, which allows you to
use straight-thru cable even when connecting to another switch/hub. Simply use the
straight-through cable for all types of 10/100/1000BASE-TX connections, either to a PC or
to a networking device such as other hub or switch.

Making your own UTP/STP cable
The twisted-pair cable provided an eight-pin plug at each end that mate with the
twisted-pair port on the adapter and with a RJ-45 wall jack. If you are marking your own
interface cables to use as dedicated network wiring or as extension cables, please follow
the guideline below:
Each UTP/STP cable contains eight wires in either 568A or
568B color scheme (please see Fig 2-7). The wires are twisted
in pairs to reduce cross talk and various signal noises.
Each pairs composed of one positive wire and one negative
wire. The positive are marked by stripe color while the negative
are marked by solid color. A pair of wires is composed of one
stripe and one solid wire of the same color.
There are four pairs of wires, they are in group of {1 and 2}, {3
and 6},{4 and 5},{7 and 8}. Please see Fig 2-8 for diagram.
When making a cable, make sure the correct pairs of wire are
twisted together before inserting into the jack. Incorrect twisted pair
will cause the cable to malfunction or signal degradation over short
distance.
A straight-thru cable has jacks on both end following the
same color scheme.
A cross-over cable have jacks on both end following the
opposite color scheme (one 568A and one 568B)
While 10/100Base-TX only use the first 2 pairs of wires (1+2,
3+6). The 1000Base-T Gigabit Copper connection uses all
4 pairs. Please make sure all 4 pairs are twisted and insert
into the jack in correct order.
